Well, it's been a while that I haven't made an OU team, as the last one I made was when Genesect was released. Who is in this team, obviously, because he's my all-time favorite Pokemon (Curse you, GameFreak for giving Slow Start to my baby .-.). Well, even though he's my favorite Pokemon, I really needed a Genesect counter. UberPwnage (UP) found a great one on ErickHill's question, and I am using that Pokemon who is Rotom-H. I have a Defensive core (Jellicent and Jirachi), paired with a very strong VoltTurn core (Rotom-H and Genesect) and I also added a Dragon destroyer (Mamoswine). For the last member, I struggled a bit. I needed a Special attacker, and I really wanted a Dragon. I went with a very unconventional but awesome Hydreigon set. Here's the team!

Well, this guy is my MVP. I can't count the number of times this guy has sweeped the opponent's entire team. It also has a very nice surprise effect. Tailwind makes him, and my whole team go faster. Draco Meteor hits very hard, and not much can tank one apart from Blissey and Chansey. Even at -2, it can nail me some OHKOs. Fire Blast is chosen over secondary STAB attack because it can downright OHKO everything in Sun. Roost is very reliable recovery. EVs give me maximum sweeping abilities, while Modest Nature over Timid because of Tailwind. Life Orb is the best Item in this situation, as Specs would be useless with Roost and Tailwind.

Rotom-H is the best Genesect counter out there. He resists all of normal Scarfed Genesect's moves, and can resist to the rare Giga Drain / HP Ground variants. Only kind of Genesect that can take him down is Techno Blast [Water] variants and HP [Water] variants. The question is: Who uses those? And the answer is: ME! But still, I don't think anyone uses those outside of Rain, and even there. Overheat roasts Genesect, and a lot of other Pokemon. Volt Switch provides momentum to my team, and makes a VolTurn with Genesect. Thunderbolt is additional STAB and is perfect for if I want to stay in. Trick can screw walls up, though I'm thinking of replacing it with HP [Grass]. Not sure.
